Sprint Booster P/N SBMA1033S. Improves throttle response. It's hard to see the improvement during the dead stop acceleration, but the difference is quite noticeable when accelerating at speed.

Wish I had a better video editor, but hopefully you guys can see the difference. During "hard acceleration", I floored the pedal from a dead stop. During "moderate acceleration", I applied approximately 25-30% throttle when cruising with engine RPM hovering around 1500 RPM.

TSC was turned off for these tests. Sprint Booster set to "Race 7".
